Innovating objects in a Eurasian center of the Late Hellenistic period.

The Assyrian Empire was the first state to achieve durable domination of the Ancient Near East, enduring some seven centuries and, eventually, controlling most of the region. Yet, we know little about how this empire emerged from a relatively minor polity in the Tigris region and how it managed to consolidate…

Archaeologists and students from Leiden University and local volunteers have found a Roman camp in the woods near Ermelo. The camp is four kilometres away from another Roman fortification discovered some time ago. This confirms the idea that the Romans would also often explore beyond the boundaries…

The Faculty of Social and Behavioural Sciences brings together high-quality research and outstanding mono- and multidisciplinary teaching.

The CS-NL network is a vibrant and active community of Citizen Science practitioners, initiators, researchers and participants from across all corners of society (Academia, Industry, Government, Civil Society, and Citizens) who come together to share knowledge and know-how for participatory research…

For the eleventh time in a row, Leiden University’s unique liberal arts and sciences programme has been awarded the ‘Top Rated Programme’ quality seal by Keuzegids universiteiten 2024.

Is it possible to formulate a new conceptual foundation for attributing an evaluative role to historiography of science, without relinquishing the historiographic sensitivity of recent work in the discipline?

When a foreign book is translated for the Chinese market, there is a good chance that not all of the text will make it into the new version. With an NWO XS grant, university lecturer Svetlana Kharchenkova will investigate how foreign authors deal with this censorship.

Archaeological Science at Leiden University is an MSc specialisation that delves into the specifics of archaeological methods and techniques. The combination of hands-on field experience and laboratory work offers a challenging and rewarding research environment.

On June 14th, Jeroen Duindam, Professor of History at the Faculty of Humanities, was awarded an exceptionally high distinction for his achievements in the field of Austrian history.

The overall objective of ECS is to widen and strengthen the European Citizen Science community through capacity building and awareness raising activities such as the creation of a European Citizen Science Academy and the establishment of a network of 28 ECS Ambassadors.

PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

On the initiative of Leiden Law School’s Art Committee, the festive opening of the photo exhibition of the Leiden Amateur Photographic Society (LAFV) took place on Friday 20 May 2022 in the C corridor of the Kamerlingh Onnes Building.

Our MSc students in Life Science and Technology (LST) specifically learn to understand the molecular and structural chemical and biological aspects…

In the master’s specialisation Computer Science and Business Studies, you combine high quality research in Computer Science with training in management and entrepreneurship. You will expand your knowledge of computer science and develop business and organisational skills that are essential to become…

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

Quasicrystals are crystals with ‘impossible’ five-fold symmetries, which nevertheless were synthesized in the lab in 1982. Paul J. Steinhardt helped figure out their structure, but he didn’t stop at that.
